FRONT WIPER MOTOR PROTECTION FUNCTION
 IPDM E/R may stop the front wiper to protect the front wiper motor if any obstruction (operation resistance)
such as a large amount of snow is detected during the front wiper operation.
 At that time turn OFF the front wiper and remove the foreign object. Then wait for approximately 20 seconds
or more and reactivate the front wiper. The wiper will operate normally.

DescriptionINFOID:0000000003761613
The front wiper does not operate under any operating conditions.
Diagnosis ProcedureINFOID:0000000003761614
1.CHECK WIPER RELAY OPERATION
IPDM E/R AUTO ACTIVE TEST
1. Start IPDM E/R auto active test. Refer to PCS-11, "
Diagnosis Description".
2. Check that the front wiper operates at the LO/HI operation.
CONSULT-III ACTIVE TEST
1. Select“FRONT WIPER” of IPDM E/R active test item.
2. With operating the test item, check front wiper operation.
Is front wiper operation normally?
YES >> GO TO 5.
NO >> GO TO 2.
2.CHECK FRONT WIPER MOTOR FUSE
1. Turn the ignition switch OFF.
2. Check that the front wiper motor 30A (#60) fuse is not fusing.
Is the fuse fusing?
YES >> Replace the fuse after repairing the applicable circuit.
NO >> GO TO 3.
3.CHECK FRONT WIPER MOTOR (GND) OPEN CIRCUIT
1. Disconnect front wiper motor connector.
2. Check continuity between front wiper motor harness connector and ground.
Does continuity exist?
YES >> GO TO 4.
NO >> Repair the harness or connector.
4.CHECK FRONT WIPER MOTOR OUTPUT VOLTAGE
CONSULT-III ACTIVE TEST
1. Disconnect front wiper motor connector.
2. Turn the ignition switch ON.
3. Select “FRONT WIPER” of IPDM E/R active test item.
4. With operating the test item, check voltage between IPDM E/R harness connector and ground. Lo : Front wiper LO operation
Hi : Front wiper HI operation
Off : Stop the front wiper.

< SYMPTOM DIAGNOSIS >
FRONT WIPER DOES NOT OPERATE
Is the measurement normal?
YES >> Replace front wiper motor.
NO >> Replace IPDM E/R.
5.CHECK FRONT WIPER REQUEST SIGNAL INPUT
CONSULT-III DATA MONITOR
1. Select “FR WIP REQ” of IPDM E/R data monitor item.
2. Switch the front wiper switch to HI and LO.
3. With operating the front wiper switch, check the monitor status.
Is the status of item normal?
YES >> Replace IPDM E/R.
NO >> GO TO 6.
6.CHECK COMBINATION SWITCH
Perform the inspection of the combination switch. Refer to BCS-76, "
Symptom Table".
Is combination switch normal?
YES >> Replace BCM. Refer to BCS-78, "Exploded View".
NO >> Repair or replace the applicable parts.

PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000003761618
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the “SRS AIRBAG” and “SEAT BELT” of this
Service Manual.
WARNING:
 To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in
the event of a collision which would result in air bag inflation, all maintenance must be performed by
an authorized NISSAN/INFINITI dealer.
 Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal
injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see the “SRS AIRBAG”.
 Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Ser-
vice Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness
connectors.
Precaution for Procedure without Cowl Top CoverINFOID:0000000003761619
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
